The objective of creating this self-powered chassis for the Army was to use
as many serially produced parts from 
GAZ-A
as possible. Mainly, it was planned to keep the GAZ-A drive axles and the bevel
gears of the main gear. The decision not to use worm gear was simply
technological since GAZ engineers only mastered worm gear by the end of 1934
with the production of GAZ-AAA. Construction of this vehicle begun in 1933 and
in 1934 the "October Horn" plant already produced a few hundred of
these chassis for use with 76 mm caliber "dynamic reaction" gun of
engineer Kurchevskiy. A lengthened frame of GAZ-A was taken and an additional
drive axle was added at the rear; but for getting enough torque from the 40 h.p.
engine the bevel gears of GAZ-A transmission with 4.44 ratio were not
sufficient. So, bevel gears from GAZ-AA had to be used, but they tuned out to be
too bulky for the compact gearbox housing of GAZ-A and so they had to be made
thinner. During the process of thermal treatment these thin gears would become
distorted and when the main gear was running a "howling" sound would
result. The shortness of time allow for the design of this vehicle had its toll
because whenever the rear bogie would encounter uneven ground with obstacles the
rear brakes would jam. The car was agreed to be unsuccessful and its manufacture
stopped.
